Definition: The rare state of already knowing that banging your ex would be catastrophic before it even happens. You possess the crystal-clear hindsight usually only granted after orgasm, allowing you to wisely dodge a bullet you know would rot your soul, reignite drama hell, or torch your current happy relationship. > “Best sex ever? Sure. But the thought of seeing his face? Instant post-nut clarity preload. I’d rather chew glass. My soul feels cleaner just saying ‘Nope’.” > “My wife’s awesome. That ex? Walking trash fire. The post-nut clarity preload hits just reading her name. Not worth it, not ever.”
